Diversity Analysis of Morphology and Main Agronomic Traits in Chewing Cane
摘要
Abstract
In order to develop and utilize the germplasms of chewing cane (Saccharum officinarum), the genetic diversity of 18 quality traits of 42 chewing cane germplasms was studied, and their agronomic traits were cluster analyzed. The results showed that genetic diversity indexes of quality traits were high, among which the internode color after exposed and bud shape were the highest at 2.074–2.011, and those of hair group in leaf sheath, bud bit, internode colour before exposed, internode shape were 1.428–1.6153, those of leaf posture, wax band, inner auricle shape were 1.1918–1.2869, and those of stalk shape, leaf stripping, outer auricle shape were the lowest at 0.3712. Cluster analysis showed that all 42 germplasms of chewing cane could be divided into 4 groups by agronomic traits, including high stalk and dense type, medium diameter and stalk type, medium to large diameter and high stalk type, and short stalk and sparse type. These could provide scientiifc basis for variety breeding of chewing cane.关键词
